Spectrum King is the first company to provide Full Spectrum LED grow lights to both the commercial and home growing community. We design our LED grow lights to mimic the sunlight because that is what plants need. Unlike other LED grow lights, SKLED distances their competitors by having one of the largest PAR ranges, as well as high lumens count. Plants need more than just ultraviolet or red light; they need the Full Spectrum of colors for their grow cycle (including Blues, Reds, etc.).
